Default [Q] i747 stuck on cm10.2 boot loop and unable to flash using odin


I have a i747 that was running the official 4.3 rom from at&t. I flashed TWRP recovery and then booted into TWRP to flash cm10.2. Everything went fine until here, but now the phone is stuck on a boot loop and I'm unable to flash even the original sammy roms using odin. I have attached the screenshot of the errors that I'm getting and also a picture of the stuff that's written at the top of the screen when in download mode.

Before I was using the official 4.3 touchwiz rom, I have been previously using cyanogenmod some time ago.

Any help would be appreciated. I have gone through a lot of threads in this forum but I'm unsure if this a soft brick situation.

I saw this link,
and followed the instructions provided in the reply and got a working phone now.
I'm still not quite sure if I'll be now able to flash stock roms using odin. I'll try that and post the results or further questions if I have any.
